This study used the Donabedian framework to explore the interdependent components of structure, processes and outcomes of the OMT response.
Phase 1 examined the relationship between structures and outcomes. Phase 2 examined both the relationship between structures and processes, as well as between processes and outcomes.
Table 1.
Characteristics of WSLHD RACHs, by year of operation as of 1 July. Ability to cohort residents, dementia specific sections, number of floors and distinct sections are all self-reported from homes. Number of homes administered refers to the number of additional sites operates by the same provider in NSW.
Fig 2.
Timeline of WSLHD RACH notified outbreaks, by outbreak type between June 2021 and December 2022.
Each count on the y-axis represents a week in which a home spends at least one day in outbreak. Outbreaks which continue across multiple weeks are represented multiple times along the x-axis. Visitor outbreaks represent declared home outbreak where a COVID-19 positive visitor attended the home, an outbreak was declared, with no subsequent staff or resident cases.

Timeline of outbreaks in WSLHD, by type of outbreak.
Each cell represents a week in which the home was in outbreak for at least one day. Each value on the y-axis represents a single home in WSLHD.

Rate of resident cases, hospitalisations and death in Western Sydney aged care residents, outbreak period and home characteristics, per 1,000 person years at risk. For the Delta period, time at risk was calculated from the first case of local transmission in NSW – 16 June 2021. For the Omicron period, time at risk was calculated from 1 January 2022 to 31 December 2022.
